samba - Aug 2023 - Samba recycle bin excludedir doesn't work for me

Hello,

I'm testing the "recycle: excludedir" option of Samba recycle bin
but
for some reason every deleted file is sent to the recycle bin, even 
those in excluded paths. Using samba/focal-updates,now 
2:4.15.13+dfsg-0ubuntu0.20.04.4.

This is the config for that share:

---
[SHARE1]
 ??? path = /isp/SHARE1
 ??? browseable = no
 ??? force create mode = 0660
 ??? force directory mode = 0660
 ??? directory mask = 0770
 ??? valid users = @"Domain Admins", @"GPO-Usuarios"
 ??? read list  ??? write list = @"Domain Admins",
@"GPO-Usuarios"
 ??? admin users = @"Domain Admins"
 ??? vfs objects = acl_xattr full_audit recycle
 ??? full_audit:prefix = %S|%u|%I
 ??? full_audit:failure = openat mkdirat renameat unlinkat pwrite pread 
connect disconnect
 ??? full_audit:success = openat mkdirat renameat unlinkat pwrite pread 
connect disconnect
 ??? hide unreadable = yes
 ??? hide unwriteable files = yes
 ??? recycle: versions = Yes
 ??? recycle: excludedir = /tmp|/var/tmp|_RFOLDERS
 ??? recycle: directory_mode = 0700
 ??? recycle: repository = _RecycleBin
 ??? recycle: inherit_nt_acl = Yes
 ??? recycle: keeptree = Yes
---

If I understood well, items deteled from \\SHARE1\_RFOLDERS (that is, 
/isp/SHARE1/_RFOLDERS) should not go to the recycle bin... but the do.

I've tried a few things but none worked so far:

- Set just one path as "excludedir =" argument, just in case the 
delimiter isn't a pipe. I've seen examples with commas, spaces and 
pipes, which one is correct?

- Set the full real path /isp/SHARE1/_RFOLDERS.

- Tried with and without forward slashes in the path (/_RFOLDERS, 
/_RFOLDERS/, _RFOLDERS/, _RFOLDERS).

- Tried with and without wilcard(s) at the end of the path.


Should this work like I think it should? What could I be doing wrong?

Thanks in advance.
